An apparatus is provided for converting coal to gas, liquid and solid products. The coal is subjected to a pyrolysis reaction at a temperature of at least about 260. degree. C. in the presence of a hydrogen-containing gas, and the resultant solid residue subjected to a gasification reaction with oxygen and steam at a temperature of at least about 482. degree. C. thereby generating the necessary hydrogen-containing gas for the pyrolysis reaction and producing a solid product. Heat generated in the exothermic gasification reaction is transferred to the pyrolysis reaction, so the apparatus does not require any external source of heat except for means (88) to control the temperature of the gases passing to the pyrolysis reaction chamber. The gaseous fraction generated in the pyrolysis reaction is cooled to produce liquid and gas products, preferably after having first been subjected to a Fischer-Tropsch reaction.

An apparatus is provided for converting coal to gas, liquid and solid products, which comprises a single vessel including a pyrolysis chamber (20) disposed in the upper part of the vessel, and a gasification chamber (29) disposed beneath the pyrolysis chamber in the lower part of the vessel. The coal is subjected to a pyrolysis reaction at a temperature of at least about 260. degree. C. in the presence of a hydrogen-containing gas, and the resultant solid residue subjected to a gasification reaction with oxygen and steam at a temperature of at least about 482. degree. C. thereby generating the necessary hydrogen-containing gas for the pyrolysis reaction and producing a solid product. Heat generated during the exothermic gasification reaction is also transferred from the gasification chamber to the pyrolysis chamber for the endothermic reaction therein by conduction through a common dividing wall (74) interconnecting the two chambers. The gaseous fraction generated in the pyrolysis reaction is cooled to produce liquid and gas products, preferably after having first been subjected to a Fischer-Tropsch reaction.

In a preservation system for a volatile memory associated with a nonvolatile memory, an energy storage portion accumulates energy while power is provided normally. When a power outage occurs, the stored energy is supplied to the volatile memory. Enough backup power is stored to accommodate the vast majority of unintentional interruptions of power. Eventually, after removal of external power, when the backup power decreases to a predetermined amount, data in the volatile memory is transferred to the nonvolatile memory. The preferred use for the preservation system is in an environment with vibration and/or power switching transients that affect the supply of power, such as an aircraft.

A system for operating a combustor in a non-Premix mode of operation includes a combustor comprising a plurality of primary fuel nozzles annularly arranged around a center fuel nozzle, a fuel supply system that is fluidly coupled to the plurality of primary fuel nozzles and the center fuel nozzle, a steam injection system that is fluidly coupled to the fuel supply system and to at least one of the plurality of primary fuel nozzles or the center fuel nozzle and a controller. The controller is electronically coupled to the fuel supply system and the steam injection system. The controller is programmed to initiate the steam injection system to inject a flow of superheated steam into a flow of fuel from the fuel supply system upstream from at least one of the plurality of primary fuel nozzles or the center fuel nozzle during a non-Premix mode of operation of the combustor.
